attribute_nucleotide_exchanges: Attribute the nucleotide exchange for an SNV

In eilslabs/YAPSA: Yet Another Package for Signature Analysis

Description

SNVs are grouped into 6 different categories (12/2 as reverse complements are summed over). This function defines the attribution.

Usage

attribute_nucleotide_exchanges(in_dat, in_REF.field = "REF",
  in_ALT.field = "ALT", in_verbose = FALSE)

Arguments

in_dat	VRanges object or data frame which carries one column for the reference base and one column for the variant base
in_REF.field	String indicating which column of in_dat carries the reference base if dealing with data frames
in_ALT.field	String indicating which column of in_dat carries the variant base if dealing with data frames
in_verbose	Whether verbose or not.

Value

A character vector with as many rows as there are in in_dat which can be annotated (i.e. appended) to the input data frame.

Examples

test_df <- data.frame(
 CHROM=c(1,1,1,2,2,2,3,3,3,4,4,4,5,5),
 POS=c(1,2,3,4,5,6,1,2,3,4,5,6,7,8),
 REF=c("C","C","C","T","T","T","A","A","A","G","G","G","N","A"),
 ALT=c("A","G","T","A","C","G","C","G","T","A","C","T","A","N"))
test_df$change <- attribute_nucleotide_exchanges(
 test_df,in_REF.field = "REF",in_ALT.field = "ALT")
test_df
